We propose an approach to timbral remapping, a process which maps the timbre variations of one audio source onto the timbre variations of another, for real-time control of synthesis. Puckette (ICMC, 2004) has made a foray into such a concept, but there are two important issues which must be addressed: how best to construct the timbre space for remapping purposes; and how to perform this remapping eficiently in real-time. We review some of the acoustical features used in the literature to...

We describe a new method for preprocessing STFT (Short-Time Fourier Transform) phase-vocoder frames for improved performance in real-time onset detection, which we term “adaptive whiteningâ€. The procedure involves normalising the magnitude of each bin according to a recent maximum value for that bin, with the aim of allowing each bin to achieve a similar dynamic range over time, which helps to mitigate against the influence of spectral roll-off and strongly-varying dynamics. Adaptive...
